Sample itemWhich nerve is at risk during thyroid surgery and can cause hoarseness if injured?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Recurrent laryngeal nerve
The recurrent laryngeal nerve supplies most intrinsic laryngeal muscles and lies close to the thyroid gland, so injury can impair vocal-cord movement and cause postoperative hoarseness or airway issues if bilateral.
Option by option
A. Greater occipital nerve
Greater occipital nerve supplies posterior scalp sensation.
B. Phrenic nerve
Phrenic nerve injury affects diaphragm function rather than voice.
C. Recurrent laryngeal nerve (correct)
Correct: recurrent laryngeal nerve injury can impair vocal-cord movement.
D. Facial nerve
Facial nerve injury affects facial expression rather than vocal cords.
